Hi, I am Scott Paul, a leading exterior restoration contractor and business owner with over 30 years of experience in exterior deck brightening and prep. My wood brightening tips are based on my history as a wood and deck restoration contractor and actual hands-on testing. See here for more info about me.
- A deck brightener neutralizes the high pH left by cleaners or strippers, restoring wood to its natural acidic state for better staining.
- Brightener opens wood pores, allowing deck stain to penetrate more evenly and improving both appearance and longevity of the finish.
- Skipping brightener leads to blotchy stain absorption, premature stain failure, and a dull look instead of the wood's natural color.
- Thorough rinsing after applying brightener is critical. Leftover acidity causes poor adhesion, uneven color, and early stain failure.
- Species like cedar, redwood, ipe, and mahogany especially benefit from brightener for proper color restoration and stain penetration.
What Is a Deck Brightener and Why Use One? (Updated for 2026)
As someone who has been restoring decks for over 30 years and tested hundreds of products, I can say this: applying a deck brightener after cleaning or stripping is one of the most overlooked steps in deck preparation. Yet it’s also one of the most important if you want your deck staining to look great and last.
If you have any questions, drop them in the comments below!
What Does a Deck Brightener Do?
A deck brightener (also called a wood brightener or neutralizer) is a liquid solution applied after you clean or strip your deck. Its main purposes are:
-
Neutralizes the cleaner or stripper – Most deck cleaners and strippers are high in pH (alkaline). Brightener balances the pH so the wood is restored to a natural, acidic state.
-
Opens wood pores – Brightener allows the deck stain to soak in more evenly, improving penetration and longevity.
-
Restores natural color – It brings weathered or darkened wood back to a lighter, more natural tone, especially after stripping.
-
Removes tannin and rust stains – Helps minimize discoloration caused by leaves, nails, or tannins in the wood.
Why Skipping Brightener Is a Mistake
Over the years, I’ve seen countless homeowners apply a stain after cleaning but skip the brightener step. The result?
-
Blotchy or uneven stain absorption
-
Premature stain failure from poor penetration
-
A darker, sometimes dull look instead of the wood’s natural beauty
Simply put, if you want your stain to last, brightener isn’t optional—it’s required.
How to Apply a Deck Brightener
Here’s how I recommend applying it based on decades of job-site experience:
Step 1: Clean or Strip the Deck
Before using a deck brightener, you need to clean or strip the wood surface.
- If your deck has dirt, mold, or mildew, use a sodium percarbonate-based oxygenated deck cleaner.
- If you have an old or failing stain, a deck stain stripper is recommended.
These cleaners effectively remove contaminants but also raise the wood’s pH, making it more alkaline. This is why a deck brightener is needed—to neutralize the pH and prepare the wood for staining.
💡 Pro Tip: Always use the same brand of deck brightener as the cleaner or stripper for the best results.
Step 2: Apply the Deck Brightener
A deck brightener (or deck neutralizer) is an acid-based solution that:
- Neutralizes the cleaner or stripper
- Lowers the wood’s pH
- Opens the wood pores for better stain absorption
- Restores the natural beauty of the wood grain
Using a deck brightener is a standard professional practice. By incorporating it into your prep routine, you’ll enhance the final appearance and longevity of your deck stain.
💡 Pro Tip: Use a pump sprayer for an even application while the wood is still wet after cleaning.
Bonus Step: Rinse the Deck Brightener Thoroughly
One of the biggest mistakes I see is not rinsing the brightener properly. If the brightener isn’t fully rinsed, the wood remains highly acidic, which can cause:
- Uneven stain penetration
- Blotchy or streaky appearance
- Poor adhesion and premature stain failure
My Test Results:
I conducted a test using Restore-A-Deck Wood Stain in Dark Walnut on two boards:
- Left board – Stain applied after rinsing the brightener for 20-30 minutes
- Right board – Stain applied without rinsing the brightener properly
The result? The right board showed poor adhesion and an uneven finish due to the leftover acidity.
💡 Pro Tip: Rinse your entire deck (not each board) for at least 15-30 minutes using a garden hose or pressure washer.
Pro Tips From the Field
-
Always brighten cedar and redwood—these species especially benefit from pH balancing.
-
Don’t worry if you see some “fuzzies” after cleaning; brightener helps reduce this and evens the grain.
-
On hardwoods like ipe or mahogany, brightener is critical for color restoration.
-
If you strip a solid or semi-solid stain, brightener helps prep the raw wood you’ve uncovered.
Final Word
Using a deck brightener is a quick, inexpensive step that pays off with better stain penetration, richer color, and longer protection. After restoring thousands of decks, I can tell you: brightener is just as important as cleaning. Skip it, and you’ll be re-doing your deck sooner than you’d like.
Recommended Deck Brighteners
Over the years, I’ve tested just about every deck prep product on the market. These are the brighteners I recommend because they consistently perform well and give homeowners the results they want:
-
Restore-A-Deck Brightener
My go-to for most projects. Eco-friendly, easy to mix, and restores the wood to a natural color after cleaning or stripping. Works on all exterior wood types. -
Gemini Restore Kit (Cleaner + Brightener)
A powerful two-step system. The brightener in this kit does an excellent job of neutralizing cleaners and prepping the surface for stain, especially after stripping old coatings. -
Defy Wood Brightener
Simple, effective, and reliable. It works especially well for neutralizing after heavy-duty stripping jobs and for bringing cedar and redwood back to life.
Best Wood Deck Brightener
If you’re unsure which brightener to choose, Restore-A-Deck Brightener is the safest bet. It’s highly versatile and the product I personally use on hundreds of jobs each year.

Deck Brightener FAQ
Do I really need to use a deck brightener?
Yes. Brightener isn’t just about making the wood look lighter—it restores the pH balance after cleaning or stripping, opens the wood grain for better stain absorption, and helps ensure the stain lasts longer. Skipping it often leads to uneven color and premature failure.
What’s the difference between a deck cleaner and a brightener?
A deck cleaner removes dirt, mold, algae, and gray wood fibers, while a brightener neutralizes the cleaner’s high pH and restores the natural wood tone. Think of cleaner as the “scrub” step and brightener as the “conditioning” step that prepares wood for stain.
Can I apply brightener to dry wood?
No, it works best when applied to damp wood immediately after cleaning or stripping. The moisture helps the brightener penetrate and do its job effectively.
How soon after using brightener can I stain my deck?
Once the wood is fully dry—usually 24–48 hours depending on weather—you can apply your deck stain. Always check that the surface is completely dry before staining.
Does hardwood like IPE or mahogany need a brightener?
Absolutely. Exotic hardwoods especially benefit from brightener because it restores their rich color and allows penetrating stains to soak in more evenly.
Can brightener remove all stains and discoloration?
Brightener will remove tannin and rust stains and lighten darkened wood. However, deep discoloration from mold or an old solid stain may still need sanding or stripping in addition.

Have Deck Brightening Questions?
Still unsure about deck brightening or the process? Drop your questions in the comments below—I’m happy to help! Also, check the existing comments—you may find your question has already been answered.
First time using a brightener on my ipe deck and I’m worried I didn’t rinse the brightener off enough yesterday. Is this fine? Do I need to worry about the darker spots vs lighter? Or is this fine and ready for the stain in 48hrs?
That is old stain where it is darker and it will look uneven when you apply a coating as it is now. To fix, you need to strip off the remaining stain and then brighten again.
Is it safe to strip the entire deck again or should I spot touch the darker points?
Strip all is correct. You might want to use a better pressure washer. The electric one you have does not have enough PSI and GPM, making it harder to strip then it should. Use a gas pressure washer if possible.
Thanks for all your help! I stripped again and most of the deck is clean, but this section still has some patches. Are these big enough to mess up the oil coat? So do I need to strip again?
Looks good to me!
A few oops marks from my pressure washing are showing through the oil. Is this just vanity or is it a reflection of how well the oil has penetrated those spots? Either way, is there anything I can do to correct it? Next time I reapply I’ll sand everything to correct a few boards with some cupping, so it’ll get sorted then if there’s no easy fix now.
Thanks again for all the advice!
Nothing you can do now. It will even out when you redo it in the future.
Hi! I am trying to clean up the white patches without redoing the entire deck. Is it possible to just do the cleaning and brightening? I want to get close to the weather dark on the left? Thanks for your help.
No, you have worn stain. The only way to fix this is to strip it all down to the bare wood and then recoat. Make sure to use a proper hardwood stain when done with the prep:
https://www.deckstainhelp.com/hardwood-deck-stains/
panicking, time is of the essence, supposed to be staining tomorrow, Sunday 3/29/26
Really hoping someone can pop a quick answer back 1133am CDT Sat 3/28
We have cleaned, brightened with the defy products which did amazing the prior two years – mistake made was that I was scared to use oil, so did water based clear sealer, which is the devil.
Finally flipping to oil now
We are doing all of this ourselves, have had a professional deck guy helping mentor us with advice
He looked at it and said that he thinks I should do more rinsing because of the white areas still showing in between the grain, still remaining after sanding with 80 grit on cedar-in Omaha Nebraska if that makes a difference
I am really dreading starting the whole rinsing process all over again, and waiting for low moisture content to 13% at least.
I have the time off these next several days to get this done before precipitation starts hitting us on Wednesday
Will you please look and tell me if you feel that it is necessary to do yet another rinse session, as I’m already 50 hours into this myself with physical challenges; and while I don’t wanna have to start the rinse process again, I certainly don’t want all of this time invested only to end up with residual leeching through the stain once supplied – if, another final rinse truly is needed.
we’re starting to wonder if maybe this person is hoping that we get frustrated enough to hire him to finish the job, although that’s not an option as we cannot afford it
I do know that the 1 post photo I am sending to you definitely needs to re-rinsing, it is clear that that layer is definitely bleaching through
But I am not convinced yet, that the rest of the deck and beams need an entire re-rinsing
And I do understand “furries” and that we do have some still present despite sanding
You are overthinking it. Looks good to stain now.
ty so much for answering on a Sunday 🥹 and confirming his advice to re-rinse is not necessary after all. so appreciate you helping all of us here, with all else you do in your arena. 🦋
If a brightener undoes the effects of a cleaner, how is Thompson’s “Deck Cleaner and Brightener” supposed to work? Would one use it as a cleaner or as a Brightener?
Because it is not a true cleaner and brightener system. Theirs is basically just bleach, which is bad for wood.
Thank-you. This site has been enlightening to say the least. So prior to seeing it, already had cleaned 7 year old, weathered, previously untreated in any manner by me, PT deck with Thompson’s wood cleaner. End result will be Defy semi-transparent cedar stain. Suggested intermediate steps? Thanks, Stephen
You are most likely okay to stain, but if you’d like to send some pictures of the prep, we can take a look. You can add them here in the comments.
Thank-you
Go ahead and stain.
How long can I wait to stain deck after cleaning and applying brightener (RAD). I cleaned and applied brightener 2 weeks ago, then it rained for 3 days, now its been 6 days since it stopped raining. Is it OK to now apply the stain?
Thanks, L Friel
Yes, make sure to sweep or blow off any debris.
How can I tell if the brighterner has been washed off well?
I rinsed each board twice/three times using power washer.
Some board that have dried since the brightening and washing, still have a slight white powdery layer on them.
Thank you
P.S. how does one include photo attachments to the messages?
No more suds when rinsing. You can use the attachment symbol in bottom right to upload pics.
Apparently, the attachment symbol does not appear while being logged as a registered user. It appears only when logged out
The white is oxidation of the wood cells that was not fully removed during cleaning or stripping. It typically does not show when stained.
So, do you think that it’s ready for staining?
I did not see any suds when I washed it for the second time after brightening
Yes, it should be good to go.
Not sure if my previous reply went through
Here is a photo of the white powdery looking stain left after multiple rinsing with a power washer. Is this still not sufficiently washed?
Do you sand before or after brightner?
Before.
In the process of refinishing my mildewed/darkened and dirty deck, I applied Dep cleaner and then lightly powewashed it. The mess has been removed but there is still a good amount of the original semitransparent stain on the boards. Do you recommend proceeding to application of brightener before applying the same gray-colored semitransparent stain?
Add some pics in the comments.
Hi Scott! I have used the Restore-A Deck cleaner before power washing my deck, followed by the brightener application (and rinsing). I now have a few spots that I need to sand because of staining caused by flower planters (water leakage). After I complete the spot sanding, should I apply the brightener to the entire deck (again) or only those areas that were spot sanded? Thanks!
All wood, but be warned, spot sanding can lead to uneven stain application. The brightener cannot “fix” this.
We had a new deck installed a few years ago and chose to use cedar as the top and stair rails. I have been using Penofin products for cleaning and staining every year but have only just purchased the brightener to use this year, as I think the blackening of the wood stain each yr may be due to my not using it after cleaning and before staining.
I always, wipe down the wood well about 15-20 minutes after staining but by the following year it is practically black! Do you think using the brightener will help prevent this from happening?
What I’m also wondering is, is it normal to have to sand the wood after cleaning it? The wood always feels so rough after I’ve cleaned it.
The blackening is due to the Penofin Brand. It has known issues with this and why we and many people refuse ot use it:
https://www.deckstainhelp.com/penofin-ultra-red-label-stain-review/
Brightener alone will not help this. You need to strip it all off and then brighten to neutralize.
https://www.deckstainhelp.com/deck-stripping-removing-an-old-deck-stain/
We would highly suggest switching stain brands after:
https://www.deckstainhelp.com/best-semi-transparent-deck-stain-reviews/
The only good thing about Penofin it is easy to strip off 🙂
We are going to re-stain a pergola soon. I used a semi-transparent Armstrong Clark stain and plan to continue using it. The stain has held up really well. We have a lot of sun, low humidity, high altitude and very little water. I’m not worried about mold and mildew here. Do I still use a wood cleaner and brightener on top of the current stain prior to re-staining?
Yes, that is correct.
I have new pine wood on a new deck installed March 2024. I purchased Defy cleaner & brightener, however I saw your review that Restore-A-Deck stain takes much better. Can I use Defy to prep and Restore-A-Deck stain?
Yes, that will work as well.
I recently had to have the corner of my deck repaired due to a tree falling during a hurricane. My deck is just over a year old. The new wood is only 4weeks old. The deck builder told me to wait at least 1 year before sealing. I planned on sealing this next month. Do i need to cover the new wood? And if so, how? Single postal retiree with very little knowledge regarding wood. 😯
You can prep and stain it in the Spring. Do not cover the wood:
https://www.deckstainhelp.com/how-long-should-you-wait-to-stain-a-new-deck/
We applied the Armstrong Cark to the IPE deck and the results are less than thrilling. Lots of variation in color and some boards aren’t taking the stain. I’m perplexed.
That is not a stain issue but a wood issue. IPE can contain what is called Lapachol. This can rise to the surface of the wood after prep and cause this “yellow” discoloration. Does not matter what stain brand you use, if the lapachol is present, it can cause discoloration.
Thanks Scott. We’re hearing ‘lapachol” from others as well. Is there any rhyme or reason to when lapachol presents? Does it come and go? We didn’t experience this with the initial finishing 5 years ago and didn’t notice anything during the cleaning and brightening process. Is there anything we can do now to lessen the effects? We expect that we will have to reapply stain in 6-12 months due to the extreme UV exposure, is there anything we can do at that time to lessen the effects? We’re thinking a darker tint may help.
It is a very strange thing with lapachol as it can randomly rise to the surface years after the wood has been installed. I believe it is based on the wood itself and the region where it comes from, but I am not sure. We have seen this happen in about 10 different scenarios over the past 5 years. I am guessing here, but I believe when you clean (you always have to prep) and remove oxidized wood cells you are essentially removing a “band-aid”. This causes the lapachol to rise to the surface. We see similar issues with pine decks and sap. The sap can leach out many years later after prep.
Here are a few tips we have learned about possibly removing it:
-One customer said he pressure-washed it, and it came off. I’m not sure if they reapplied the stain or not after.
-Another stated they heavily scrubbed the spots and recoated.
-A third said they used a solvent like mineral spirits to remove and then recoated.
I’ve completely sanded my cedar deck and replaced over 75% with new boards.
My question is do I need to use a deck brightener?
You still need to let the new wood weather and then prep. Did you do this?
https://www.deckstainhelp.com/how-long-should-you-wait-to-stain-a-new-deck/
The new wood has been installed over this past summer. I had put a semi solid stain on some but hated the look. I have since sanded all of the deck, avoiding chemicals.
Now that this is done, I want to stain with a semi transparent stain.
How long do I really need to wait before using the brightener?
Thanks
Mark
Brighten now and pressure wash rinse for prep. Look at TWP 1500 Series or Armstrong Clark stains. Just one coat.
Is there any eco-friendly brightener?
And thanks for your help it has been great!
Mark
Most wood brighteners are eco-friendly.
I used rustoleum/wolman to clean deck. Can I use restore deck or defy deck brightner
Yes.
I am using Oxalic Acid to clean my cedar deck. As such, do I still need to use a wood brightener as the main ingredient in wood brighteners is Oxalic Acid? Or should I use something else to clean/revitalize the cedar deck?
Oxalic acid is not a cleaner but an ingredient in some wood brighteners. It does not “clean” anything but neutralizes after using a stain stripper or a deck cleaner. You should use a proper deck cleaner first and then a wood brightener after.
Could you recommend a proper deck cleaner for a cedar deck? I am seeing recommendations for something as simple as Oxyclean but not sure if will work.
See top reviews here: https://www.deckstainhelp.com/best-deck-cleaners/
I have an ipe deck that gets a lot of Caribbean sun. It was originally finished with Cabots Australian Timber Oil and it has not performed well. There is a lot of uneven weathering and some of the deck is going gray. Nothing has been done to the deck since the original finish abiut 3 years ago. We’re stripping the deck with Penofin’s stripper and then using deck brightener. The deck looks pretty good in some areas but other areas have a lot of variation and also some dark stains that aren’t coming up. Looking for suggestions on things to try before we finish with Penofin.
Steps thus far
1. Penofin stripper
2. Penofin cleaner with agitation and low pressure power wash
3. Penofin brighter
Avoid Penofin. It has issues of darkening or turning black from the sun. There are better stains:
https://www.deckstainhelp.com/ipe-exotic-hardwood-stain-review/
As for prep. add pics for advice.
Here’s a Pic after multiple stripping/cleanings. The dark areas are where we applied stripper on some stubborn spots.
The prep looks good. 😀
I’m a little worried that there’s still a.lot of uneven color and some blotches compared to the beautiful grain of the original wood. Will the color variations be exacerbated or mitigated by the Oil finsh. I’ll be using Armstrong Clark amber. Also would like to get an idea of the recommended ongoing maintenance. The deck is in the Caribbean in full sun so there’s serious UV exposure. I expect we will have to reapply every 6-8 months. Will that be just a cleaning and reapply? Some areas in the sun will be faded whereas other areas will not. If we just hit the entire deck again will it even up.? The alternative is to not oil it and let it go gray but I love the rich color when it’s oiled
The AC Amber should highlight the grain as if wet with water. You can test the appearance by wetting it all down with water.
Just clean and reapply as needed. 😀
More pics. Let me know whether sanding will help or if this will disappear when the finish is applied.
You need to remove all of the stain in the last picture. Strip and or sand.
Here are the latest photos. There are still have some areas with color variation including some black spots, some that look like residual stain and dome areas that look bleeched. Should we continue to try to strip and/or sand or is there another approach for these areas?
The last picture shows a stain overlap from prior coatings. That will probably show when stained so try to sand that out. The dark internal spots may not come out. Best to try a wood brighener on all wood hen done to see if that helps.
Thanks. We’re continuing to strip and will also try spot sanding the blemishes …The handrails are very noticeably golden and much more dried out compared to the rest of the deck. I’m not sure why that is as it’s the same material with the same original finish. Could be just a difference in sun exposure? We’re concerned about how they will look when stained. Do you have any experience with this?
It looks to be the same wood type.
Yes it’s the same wood, wondering why the handrails now appear so much more golden and much drier compared to the rest and whether we should do anything different when applying the finish
Just the way it has weathered. I would not worry about it.
Yes it’s the same wood but it’s much more golden color and more dried out. Is there anything we can do in the process so it looks the same color as the deck after finishing? Right now it looks quite different. Prior to stripping the color looked similar although the handrails looked more dried out and weathered
One more. I’m a little worried that there’s still a.lot of uneven color and some blotches compared to the beautiful grain of the original wood. Will the color variations be exacerbated or mitigated by the Oil finsh. I’ll be using Armstrong Clark amber. Also would like to get an idea of the recommended ongoing maintenance.

Here is a photo of the weathered Cabots Australian Timber oil
Thanks for the tip on stains. We will use Armstrong Clark instead
You are welcome!

Sorry but no idea what will remove it.
When using Restore a deck to stain an older deck , what is best used to apply the stain ?
Which Restore A Deck Stain? The semi-transparent or the solid stain.
Semi transparent stain
Flooring brushes or stain pads. See this for tips: https://www.deckstainhelp.com/best-applicators-for-deck-stains/
If I pressure wash the deck and sand, do I still need to use restore deck cleaner before I use the brightener?
You use the RAD Cleaner at the same times as pressure washing.
I have completely sanded my deck and am going to apply a Pittsburgh solid stain. Should I still use deck brighter? Also, if I do need to use brighter, I have plants directly under my deck how do I prep for that??
Thank you!!!
Yes, brighten to open the grain of the wood. Cover plants while applying.
I am unclear as to rinsing time of 20-30 minutes (that’s a long time). How is that quantified? By a certain size area or the whole deck? Certainly I can’t rinse 2 or 3 at a at once for that full time.(?)
Can you better describe rinsing the brighter.
I have sanded and cleaned and purchased Defy Extreme semi transparent stain.
Whole deck. Rinse until suds are gone.
hey i accidently did not wash the brightener until 4 days later is that okay or what should i do? did not know i was supposed to wash it off until i reread the instructions. and how long can you wait till you cant wash it off and what would you do if that happened?
You should be fine but it would not hurt to rinse the wood down now.
I used Restore a Deck semi transparent stain a little over 2 years ago and need to reapply as have worn areas on stairs and top rails. I have an unopened 2.5 gallon container. Do I need to follow the complete process of stripping, cleaner and whitener again?
Clean and brighten for prep. No need to strip. When using the stain, shake it vigorously for a few minutes to mix as the pigment can settle.
My redwood porch post is 2 months old and one side has a darker shade due to sun exposure. Should I still clean and brighten before applying finish? Or should I just apply the finish since it’s only 2 months old?
You need to prep all new wood before staining. See here for tips:
https://www.deckstainhelp.com/how-long-should-you-wait-to-stain-a-new-deck/
Thank you for your time! Our deck was built June 2023. It is now Nov. 2, 2023. Pressure treated pine wood. Seems to me the uncovered area is ready. But covered and inside look not as weathered. We live in Middle Tennessee. I was hoping to seal and stain the uncovered before winter. Question we need a deck cleaner and brightener right? And I am leaning towards Ready Seal Light Oak Semi transparent, or Cabot new cedar semi transparent. We are hoping to seal and stain uncovered before a family event on Dec 1. 2023. Main question, should we seal and stain ONLY uncovered / exposed deck now before winter? And wait until spring to seal stain the interior? Your thoughts are appreciated! This is slightly overwhelming thank you so much for your time.
Do it all at once, do not break it up. You can do it now or Spring:
https://www.deckstainhelp.com/how-long-should-you-wait-to-stain-a-new-deck/
We would not suggest Ready Seal or Cabot. You can read their reviews on this site.
I was told by the rep at the Sealer Store that a brightener is not necessary to use on cumaru, just use RAD cleaner and go straight to staining, for my new (but weathered 4+ months) cumaru deck. What do you say?
We always brighten after using a cleaner or a stripper. Turns out better.
I cleaned my deck today, but didn’t have brightener on hand to apply while still wet from cleaning. If I order some brightener and apply 3-4 days after cleaning, will it still work to balance the ph and help stain soak in? Just curious if the gap in time between cleaning and brightening make the latter ineffective?
Yes. Better late than never.
Is a brightener necessary after cleaning previously stained pt wood? Last stained 2 years ago with Armstrong Clarke semi-transparent grey. (Will use for next finish) Great product. Do not think I brightened. Thank you!
We always brighten after cleaning as some of the old stain may come off when cleaning.
I stained my deck last summer and just recently cleaned it off with some Dawn soap in water. The boards still look very dull. What can I do to fix this?
You would have to recoat it.
I cleaned & brightened my deck on Friday, then the chance of rain came and now it looks like it will rain for the next 10 days! Do I cover the freshly cleaned deck with a tarp for 10+ days, (the dogs bring mud all over it) or just live on it and re do the cleaning and brightening when weather gets better? Can you clean & brighten TOO soon?
We would not cover it. Just give it a good pressure wash rinse to remove any dirt a couple of days before staining.
Thank you, but just to be sure I understand, DO NOT clean or brighten again, just power wash? I was afraid it might hurt the wood to use chemicals again so soon. 🙁
Do not cover the deck. Just wash it with water to remove any mud. You cannot hurt wood with prep products.
I have a deck with composite decking for the surface and redwood for the railing. I have a cleaner that’s designed for composite decking and natural wood decking. My question is if I use a brightener on the redwood will it have a negative affect on the composite decking?
No, it will not.
Have defy deck stain on my deck. It needs a maintenance coat. Will just a washing with dawn dish detergent be enough or should I use a wood cleaner and brightner. Thanks!!
You need a deck cleaner and then a wood brighener for prep.
Do you mind if I add this article to the FAQ section of my website? I have a deck and fence staining company out of Georgia. Will post a link to this article and credit you of course.
Sure.
This is my first deck. I was told by my contractor to use Behr penetrating oil. I’ve cleaned and treated it every other year. After only 6 years some of the wood is twisting or splitting. An associate at the lumber store said that the newer pressure treated lumber is not as good as the old green stuff, and that what I’m seeing is to be expected. Really?
I don’t see any comments about this oil. Should I switch to another product? Im not lazy, but I’m not young any more, and on my own. So looking for low maintenance.
If anyone has a suggestion I’d appreciate it. Thanks.
Yes, switch. Strip and brighten with Restore A Deck Stripper/Brightener Kits. Stain with Restore A Deck Stains or TWP Stains.
Hi,
My wife and I moved into a new house. The previous homeowners used Cabot solid stain and appeared to have put a fresh coat in the last few months prior to the sale. Everything seemed fine until the last snow of the Spring melted off and we found that the solid stain was coming up in strips.
I wasn’t planning on having to redo the entire deck but I felt I had little choice at that point. I decided that despite the fact that the deck is older, I didn’t want to have to deal with the solid stain anymore, so I started sanding with an orbital. I didn’t realize how long it would take doing it by myself. What felt like a project that would take a month has turned into a two and a half month sanding job due to the larger than normal amount of rainfall our area has had this Summer.
I’m nearly done but much of what i already sanded has turned grey due to sun exposure and there is some dark mold/mildew. Do I have to turn around and re-sand the deck again to expose fresh wood or will using the Defy cleaner and then brightener be fine? I’m using the Defy semi-transparent stain once the prep work is fully done.
Thank you for any help you can give me.
Clean and then brighten for final prep is correct and then stain.
Hi,
I have a cedar fence that I’m stripping in stages over several days with – is it ok to use your brightener product prior to staining but after all the stripping is done?
Thanks
Best to brighen as soon as possible.
Thank you
Advised to use a deck brightener with oxalic acid on my Trex deck. Which deck brightener would you recommend?
A brightener will not do anything to clean a Trex deck. You will need a deck cleaner like the Restore A Deck.
Hello, I had new cedar decks put in about a year ago and am just now having them stained. My contractor used a cleaner with a pressure washer then a brightener. After a couple days if drying he applied the stain. Bow there are light areas around the knots in the wood where it looks like the stain didn’t penatrate. What should I do?
Lighter areas around knots are normal and have to do with the density of the wood there. Not an issue.
Oh good. Thanks!
Our front porch railing was built last September, 2020 of new pressure-treated pine lumber. On July 1, 2021 we used the Restore-A-Deck Cleaner and Brightener, which highlighted some unsightly printing. So we sanded that out lightly with 60-grit sandpaper. Can we just rinse off the area thoroughly, then proceed with staining (TWP 101 Cedartone) after two dry days? Some comments seem to indicate this, while others seem to suggest that the Brightener should be used again over the whole project, to improve stain penetration. (Am I right in assuming I wouldn’t need to use the Cleaner again after my spot-sanding?) Thank you so much!
If you spot sand then the stain will take lighter in those areas. Cleaning will help even it out a little. Brightener after.
We are about to stain our brand new barn that was completed early October 2020. The exterior siding is rough cut pine board and batten.
It has started to gray slightly. We are using Armstrong Clark semi transparent Natural Oak stain. We are going to lightly pressure wash it. Should we use restore a deck wash or maybe brightner to properly prep the rough cut pine prior to applying the stain?
Thank You for your Assistance,
Greg
Use both the Cleaner and then the Brightener.
Thank you for your response.
Can the wash and brightner be applied through a pressure washer?
No.
Would deck brightener damage the paint on the side of the house if it were to splatter?
No, it should not.
Hello – We plan to sand the deck before staining it. I will be cleaning the deck a week prior to sanding and staining.
1) Should I use a chemical cleaner? If so, should I use the brightener right away?
2) When I sand next week, should I use a brightener right after? How long do I need to wait after brightener before I can stain?
Thank you for your help!
Great, thank you for your quick reply!
My husband rebuilt our deck last August. We used pressure treated pine boards. Now we want to finish the project. We will use Defy exterior deck products.My questions are as follows: 1. Can the wood cleaner and brightener be applied on the same day? Does the wood need to dry after the cleaner before the brightener? 2. Do you recommend pressure washer or broom /brush for cleaning ? 3.is it better to use stain pad or paint brush for applying the stain? 4. How many coats will it need as it is less than a year since built? Thank you your help. Your site has been very helpful Sue
What kind of safety gear is required to use deckwise brightener (and cleaner). Is it harmful if it touches the skin and eyes, inhaled?
Depends on the brand but just wear protective clothing, eyewear and gloves.
Thank you! It’s Deckwise Brightner (and also Cleaner)
Is it necessary to wear a VOC mask? Thanks in advance!
No.
Hello,
How long can I wait to apply the brightener after stripping?
Thank you in advance….
Right away while wood is wet.
How long can I wait to apply stain after stripping and applying the brightener?
1-2 weeks before prep will need to be redone.
Im repairing a pressure treated deck on a house i recently bought. Two or three boards need replacing and a few were already replaced recently but those that are solid are quite weathered. I plan to apply a semi-transparent stain in the end. Would a brightener help even out the color between the new and old wood before staining? How long should i wait to stain after replacing the boards?
A brightener will not even out the difference between new and and old. There is not a way to do that. See here about new wood. https://www.deckstainhelp.com/staining-a-new-deck/
I have an older pressure-treated deck. Last summer, I did the following:
-applied a chemical deck stripper to remove a solid stain
-sanded entire deck to remove patches/residue of stain that remained after using stripper
-replaced several rotted boards with new boards (also pressure-treated)
-allowed the newly installed boards to “weather”, at the advice of a lumber-store employee
It is now spring, the following year. The deck has weathered rain, snow, sun, foot traffic, etc. What needs to be done before I apply new stain (preferably semi-transparent) to the bare wood? Use deck cleaner? Brightener? Both? Sand again? (If you suggest sanding again, I might have to jump off a cliff;)
An image of the deck in its current condition is attached.
Thanks in advance for your advice.
Use a deck cleaner and then a wood brightener for prep on this one.
I have a raised deck with stained concrete patio below the deck. When I use the Defy Cleaner and Brighter on the deck must I cover the stained concrete to avoid damage to the stained concrete?
It should not harm the concrete. Make sure to rinse off any soap and dirt residue when done.
We connected 2 older decks with a new deck. Ive heard to not sand new deck but sand old decks. Do I need to sand before I use a cleaner?
You do not need to sand but you also cannot stain new wood right away: https://www.deckstainhelp.com/staining-a-new-deck/
Is a brightener necessary if applying a simi-solid oil base stain?
Yes.
Used the old bleach and tsp cleaning method and pressure washed twice now the areas have a white film over then….sanding is not an option bc the deck has weathered and is not flat….what can I do to remove this film??????
Post a picture.
I got a white film over my redwood siding after applying the new penetrating oil. I called the oil company people, but they hadn’t heard of that happening. So I took some denatured alcohol and rubbed the white off. Mineral spirits also seemed to work. By the way, The preparation for the siding was a bleach and tsp(as recommended by the redwood association) mixture, to clean and remove mold. Also I had applied Bore-care with mold control- after cleaning. It has been almost a year now and no white film has come back. Everything was allowed to dry, so I don’t think moisture was a factor.
I just stripped my deck using F-18 deck stripper. I’m planning to use the same stain – CWF Clear. Should I use a brightener prior to staining?
Yes.
I built a new deck 6 months ago and am getting ready to apply a solid stain.
After I use the cleaner, do I need to use a brightner too? I’m not sure if a brightner is needed with a solid stain.
You do not have to.
I’m installing a new untreated redwood deck, live in colorado. What is best cleaner and brightener to use? Is oil based or water based semi transparent stain best?
See here for new wood tips: https://www.deckstainhelp.com/staining-a-new-deck/
I have a deck that is close to ground level and doesn’t get much sun. The prior solid color stain had issues with peeling. It is now sanded but also had to replace some boards. Do I need to clean and/or brighten sanded parts, how long do I have to wait to stain new boards and do you have any recommendations for new stain, solid or not? Thank you.
Let is sit for a few months and then clean and brighten for prep. Try a penetrating stain so it does not peel: https://www.deckstainhelp.com/the-5-best-deck-stain-reviews-and-ratings/
We have Restore A Deck Cleaner and Semi transparent stain for our deck (which took 6 weeks to arrive); but no brightener. We cannot find any brighteners locally. Is there something else we can do to neutralize the cleaner or can we proceed to staining without it?
You should be okay if you rinse extremely well with water. It is not ideal but it should be fine.
Should I strip old penetrating stain if the new stain going over it is solid?
It will help the solid to adhere better if you do.
Got two questions: one concerning wood brightener and the other concerning cleaner. I’m cleaning a deck stained and will put solid stain over the top.
Would you recommend wood brightener in this situation? Since the stain is not penetrating, I didn’t know if this step is necessary.
There are some areas that are peeling that will be sanded down as well to note.
Second question is do both cleaners such as “30 Seconds (sodium hypochlorite)” and using an oxygenated powder such as OxiClean affect the pH of the wood in similar ways?
You do not have to use the brightener for this. Neither of these cleaners will work well nor would we use them for prep so hard to say which is better.
Thank you..
I’ll be cleaning -not stripping- my deck and putting the same stain over last years’ stain. Should I use a brightener or just clean the deck? Is it useless to use a brightener over old stain?
You will not need it for this scenario if you have a base coat.
I accidentally applied an acrylic water based stain over an oil based stain. Needless to say that didn’t work well. Will sanding the deck with an orbital sander down to the bare wood be enough prep to apply a new coat of the acrylic stain. (It is a solid stain)
Yes, sand to remove all.
I cleaned and brightened my deck with RAD products but weather prevented me from staining for about 10 days. During that time we got about three rain storms. Now the deck looks darker again and there are black steaks by the screws. What is my best step to pre the deck to stain now? I’m thinking of a light sanding or using brightener without cleaner. Picture included.
The black by the screws is your screws rusting. You can rebrighten the wood but it will come back once it rains again. The only way to fix would be to replace the screws.
I pressure washed and then used restore-a-deck cleaner followed by brighter to prep for re staining with an oil based stain this year and then the forecast changed. Looks like I’ll have a week of rain now before it dries out again. Do I need to rewash or reapply the brightener before I stain then?
As long as you stain within a couple of weeks of prep, you are okay.
I have a new tigerwood deck. I’ve seen quite a few posts, but I’ve yet to find one that gives step by step instructions on staining/protecting the new deck. I plan to use a hardwood stain, such as the AC hardwood stain. Please advise on the steps I need to take in preparation.
See this about new wood: https://www.deckstainhelp.com/staining-a-new-deck/
Clean and brighten and then use the AC.
Just replaced about 1/3 of the deck boards and sanded the rest to get the gray off . Should I clean and brighten the deck or leave it to weather for another year before staining. The boards that weren’t replaced were replaced 2 to 3 years ago. Or can I clean , brighten and stain now?
I sanded my cedar deck and want to apply a semi transparent stain. What do I need to do to prep the deck for staining. Do I need to put something on to help the stain to adhere? Or can I wash off the loose saw dust and the stain. I have read that a brighter would help. Any preferences?
Clean and brighten after the sanding to open up the wood grain. https://www.deckstainhelp.com/restore-a-deck-cleaner-system-review/
How about if 1/3 of the wood has just been installed within the last month. This is a continued question from before about sanding the deck
Let the new wood weather for another 2 months and then do the clean and brighten to all wood. https://www.deckstainhelp.com/staining-a-new-deck/
How do you feel about just using a
Power washer without any soaps for
Cleaning a cedar deck? Would use of a deck brightened help bring back some of the lost brightness of the cedar?
Pressure washing alone will damage cedar wood if you are not careful. A brightener by itself is not sufficient for prep. You clean first and then brighten.
i cleaned my deck yesterday and today it’s raining like the devil. Will I still need to use a brightener when the rain stops? Or will the rain be sufficient to neutralize the cleaners?
Yes, you should brighten the wood.
I have Messmers UV plus natural on my Western red cedar deck in the Seattle area. It’s relatively new wood but over a year old. It’s had one coat of messmers on it and that’s all it’s ever had. That was about 9 months ago.
Last week, I used Messmers cleaner and that caused areas that appear to not have stain. The deck looks ratty now. Before washing it looked pretty good but messmers says we should wash the deck twice a year.
Last night, I did the water test on bare looking areas as well as the stained looking areas and the water never soaked in. So I think I should put a new coat of stain to protect from UV damage but I’m afraid the stain won’t penetrate.
A week after washing, would it be a good idea to use the Messmers brightener to see if that would allow the stain to penetrate? You said something about being more acidic would help the stain penetrate and that the brightener also opens pores.
Would a year of no UV protection be a serious problem or would it be best to just wait until next year to stain it instead?
The brightener will not make a difference. You can leave until next year, you will be okay.
Thanks for your quick reply! Would it be alright to spot stain the areas that have no stain color on them? And am I correct in believing that the water test means that the oil based stain won’t soak in?
Spot staining and it will look blotchy. Water test just means the wood is absorbent or not.
Can I use a deck brightened as a Cleaner?If I have to use both which do I use first?
A brightener is not a cleaner. Use the cleaner first and then a wood brightener.
Hello. If I have an IPE deck that I want to leave grey. Would I still use a brightener after cleaning?
No need.
Thank you for this site – it answers many questions I never knew I had…
Regarding the brightening step, can you suggest any frugal or diy options that won’t harm the plants, dogs or humans? Best,
No. Brighteners are inexpensive. Buy one at your local store or online.
How much raw oxalic acid should I use per gallon for a direct spray application and should I rinse it off after letting it dwell for 10 minutes or should I just leave it on the wood to dry?
Use a true wood brightener, not straight oxalic. Much better and is buffered for wood. Always rinse after using a brightener.
I used deck cleaner on half my deck, didn’t like the results as it appears “ashy”, guess it’s oxidation maybe? I’m assuming I should have applied brightener right after? Is it too late to do this? Can I wait a few days as time is extremely limited?
I didn’t knoApplied on one year old deck, did nothing but leave a white film on deck and fuzzies from me trying to scrub. Worked really good on two plastic chairs that were covered in mildew though. But on pressure treated deck did nothing. Now I have to sand half a deck. Thank Gid I only did half. I didn’t know I had to use brightener.
The fuzzies are not from not using the brightener but this happens when removing the oxidation from a year of graying. No way around it. You should finish the cleaning, buff off the fuzzies, and then brighten.
Should I worry about that remaining “oxidation”
I wouldn’t. It will not show when you stain.
Going for a Semi-Transparent, would that be an issue?
No issues.
What is the best long lasting stain for a deck with heavy sun exposure
Try Armstrong Clark in a semi-solid color.
I think it’s very important to address how these products might affect plants in and around the deck. Would they kill them, cause I have a ton of money invested in plants under my deck.
That would vary by brand but in general, a wood brightener should not harm plants.
Hello, I’ve use a gallon of Behr Wood stripper and then applied Behr wood restorer and my solid cedar doors are still blotchy. I’ve also been sanding them to get them even. Any ideas? As for stain, I’m reading the reviews and would like any suggestions.
Does not look like it stripped off very well. Try sanding all wood to remove the rest of the coating and then brightener after to even it all out. Try a penetrating stain when done. Easier to maintain. TWP or Restore A Deck.
Should the deck be wet or dry prior to applying Restore-A-Deck brightener?
Wet.
I have cleaned and used brightner on my IPE wood furniture, 1. What happens if I miss some spots with brightner and 2. What if it’s a week due to rain before I can apply oil/stain?
You can wait a week to stain but best not to miss any spots when brightening. it may show darker when stained in those areas.
Our pressure treated pine wood deck is 9 months old. It looks very clean, however we plan on cleaning it with Defy Oxygenated Wood Cleaner. Is it really necessary to use a brightner after cleaning? Also if we do use a brightner, can we just hose brightner off? We are uneasy about using a pressure washer and do not own one. Third question is: If we miss a spot with brightner would it be obvious, before you stain?
Yes, you need the brightener to naturalize the cleaner. Apply it and rinse off. Very easy to apply and rinse.
My deck is now clean, stripped and/or sanded in some spots. The brightener can go on now, but I do not yet have the stain (I am still waiting for the samples). The temps in Spokane, Washington have begun to drop to 70 in the day, and high 40s to low 50s at night.
1. Is it too late this season (now mid-September) to apply the stain if the temps remain at these levels? Once I get the samples, I will have to wait for the stain to arrive here.
2. If I do stain, how long after the application should it NOT rain. I cannot control the rain, but how many days after application should I see clear skies in the forecast?
Thanks
1. You are fine with the temps
2. About 24 hours but it does depend on the stain brand and type.
Question about restaining a deck. I have a pergola that I stained 2 years ago. I want to restain it with the same kind of stain (CABOT AUSTRALIAN TIMBER OIL). Do I need to use a cleaner and a brightener before I restain it. If not the brightener why not?
Thank you,
Jim
Yes, you have to prep. Use a deck cleaner if using the same brand and color of the stain as last time.
So no need to use a brightener to neutralize the cleaner?
You can but you do not have to unless your prep removes the old ATO. Then you would brighten.
Thank you!!
How many days should the deck wood be totally dry before applying the stain as a rule of thumb.
Do you have any recommendations on keeping the stain going on thin ie using brushes vrs rollers etc.
48 hours is normal. Use exterior deck staining pads for applying.
I’ve stripped the deck of all the old stain over a number of weeks in April/May using Behr no 63. I’ve washed the deck often but now I realize I should have used a deck cleaner in April/May as opposed to now before I stain (in Sept). I plan to use the cleaner and then wait 3-5 days for drying before staining, Do you have any advice given that there were a number of months now where I didn’t neutralize the Base cleaner. I live in the Pacific where it rains constantly so the deck was often wet.
Just use both a deck cleaner and a wood brightener and you should be okay.
How does sodium percarbonate based oxygenated cleaner affect nearby shrubbery? What precautions must be taken when using it?
We just prewet and rinse immediately any overspray and never have any issues.
I am getting ready to stain a deck that was built last Sept. with pressurized wood and has never been stained or treated with anything. I understand that cleaning is important prior to staining. My HOA specifies a solid stain and I’m planning to use a Flood solid stain product in a chocolate color to match the HOA requirements. Is brightening still recommended even though the grain of the wood won’t show through the solid stain? One of the folks I consulted about doing the deck did not include it after I asked for it and said that it was unnecessary with a solid stain.
Technically no it is not needed when using a solid stain.
Is brightening generally just applying and a thorough rinsing? Or is a very light agitation of the wood with a scrub brush required and/or power washer? Thanks!
Just apply and rinse after 15 minutes.
I’m restaining a 2 story deck. The underside is stained and looks fine. The rails are still stained. The deck boards and rail cap are completely bare and weathered, but in great condition. I want to use TWP 100 series 102 redwood on the deck. If I strip and clean the floorboards, the stripper will run down onto the floor joists and partially strip the underside leaving a huge mess. Can I just use a deck brightener to prepare the floorboards for staining without affecting the deck underside?
No. When you switch brands you have to remove the previous coatings on the railis. You would clean and brighten the floors if already bare.
I’m looking to start making boat docks look more pleasing. Of course there on a lake with full sun and lake water. Is this product what I should use on these or do you have another one to try? Thanks in advance.
For prep you need both a cleaner and a wood brighener. For the stain, try Restore A Deck wood stains.
You say “A simply application of deck brightener after cleaning ” I think you mean “simple”. Good lookin out!
Thanks!
I power washed my deck that was in bad condition. I’m not a pro at this and really gouged the wood with the power washer in areas. Despite that there’s still paint in some areas so now I’ve been sanding it off. This is very labor intensive. If I buy a stripper product how easily will the paint come off. Additionally, if I’ve sanded the wood is it really still necessary to put a cleaner on the deck. I don’t have tons of time to work on this deck. Thanks.
Strippers do not remove paint. If you sand, yes you should finish with a deck cleaner.
Washing stripper off deck will the stripper strip the vertical wood that is ok
If it gets on the vertical wood, it will take it off.
I do not want to darken my decking with a stain after oxybleaching is there a protective solution I can paint on that is colourless and do I need to use a wood brightener after bleaching?
A clear sealer without any tint will not protect the deck from UV and will gray. If you want UV protection from graying, then you must use a stain and that will darken the color.
Yes on the wood brightener.
Just to add, I live in the northeast which is why I am running short on time!
I have a 1 year old garage with pine siding. i was going to stain it this year with twp 1500 but am concerned that I do not have time to do it correctly using a brightener first. Am I ok to wait one more winter and apply stain in the spring?
You need to use a cleaner first and then brightener. Brightener alone will not do the proper prep. You should be fine to prep and stain in the Spring.
I’ve got a 13-year old cedar deck that I’ve sanded down to the wood and I’m about to stain with TWP 1500… how important is it that I use clean and brightener before I stain since it’s now raw sanded wood? I bought Olympic brand brightener & cleaner from the store because it was cheap, should I return it and buy the more expensive Restore a Deck ($60)? Many thanks!
Best to prep after the sanding. It will help the stain to soak in. We are not fans of the Olympic since it contains bleach. The RAD product are not expensive considering they contain a cleaner and a wood brightener and make 5 gallons for each.
decking boards were new 2 yrs ago with treated cedar–i would like to use a brightener now that i have power washed and will give it a few days in our 90 plus iowa heat to be well dried–need for the finished appearance to be very light cedar color as new but would like a bit of gloss
Do not add a shiny or gloss coating to decking. It will peel and create a huge mess to fix. Best to use a fully penetrating stain. As for the brightener, any quality brand should work.
If it rains after I brighten my deck, can I still stain (after 2 additional days of drying time) without reapplying the brightener?
Yes. Rain does not harm the brightener.
I stripped off our old stain and then put a brightner on it some of the boards look really nice but some have a black tent to them is it OK to use the brightner a couple times? The stain came off pretty good with the stripper. I did 10 foot sections and after I stripped it I put the brightber on it right away before I move to the next 10 foot section to strip. Can I stripped the rest of the deck and wait to put the brightener all at once on when I’m done? Confused on this.
